BACKGROUND It is not clear whether the benefits of tracheostomy remain the same in the population. This study aimed to better examine the effect of tracheostomy on clinical outcome among prolonged ventilator patients. METHODS Data were from the medical claims data in Taiwan. A total of 3880 patients with ventilator use for more than 14 days between 2005 and 2009 were identified. Among them, 6...
BACKGROUND Mechanical ventilation (MV) is a key component in the care of critically ill and injured patients. Weaning from MV constitutes a major challenge in intensive care units (ICUs). Any delay in weaning may increase the number of complications and leads to greater expense. Nurse-led, protocol-directed weaning has become popular, but it remains underused. The aim of this study was to ident...
BACKGROUND In pressure support ventilation (PSV), a non-variable level of pressure support is delivered by the ventilator when triggered by the patient. In contrast, variable PSV delivers a level of pressure support that varies in a random fashion, introducing more physiological variability to the respiratory pattern. Experimental studies show that variable PSV improves gas exchange, reduces lu...
OBJECTIVE The use of the rapid shallow breathing index (RSBI) is recommended in ICUs, where it is used as a predictor of mechanical ventilation (MV) weaning success. The aim of this study was to compare the performance of the RSBI calculated by the traditional method (described in 1991) with that of the RSBI calculated directly from MV parameters. METHODS This was a prospective observational ...
The ventilator discontinuation process is an essential component of overall ventilator management. Undue delay leads to excess stay, iatrogenic lung injury, unnecessary sedation, and even higher mortality. On the other hand, premature withdrawal can lead to muscle fatigue, dangerous gas exchange impairment, loss of airway protection, and also a higher mortality. An evidence-based task force ha...
Mechanical methods of euthanasia have distinct welfare advantages, since when the methods are employed correctly animals are rendered instantly unconscious and hence unable to experience pain, fear or distress. When personnel are skilled and equipment is well maintained, death is rapidly and humanely induced, but these methods can be aesthetically disturbing for some people. Mechanical methods ...
This paper presents a review on application of wavelet transform for condition monitoring and fault diagnosis of mechanical equipment. The discrete wavelet transform performs a multilevel signal decomposition to extract fault features from the vibration signal. A review on all the literature of condition monitoring using wavelet transform is certainly not possible. The purpose of this review pa...
The complexities of mechanical ventilators have been chronicled in these pages over the last few decades as investigators and manufacturers have searched for improved outcomes and competitive advantage. On several occasions I have had the privilege of writing about the current state of the art and the promise of closed-loop mechanical ventilation.1–3 While new modes of mechanical ventilation ha...
Ventilator-associated pneumonia, broadly defined as pneumonia that develops after 48 hours of intubation, is a common mechanical ventilation complication that causes significant morbidity and mortality in critically ill patients. Prevention strategies are continually evolving to decrease the impact of this serious and costly disease.
This paper reviews management strategies for patients undergoing prolonged mechanical ventilation (PMV). Topics covered include how to identify and correct barriers to weaning, the systematic approach to weaning trials, when to cease weaning trials and proceed with life-long support, managing the tracheostomy tube during PMV, and, finally, how to select a suitable mechanical ventilator for PMV.
